Welding is the common core into all trades. Requiring precise hand skills and dedication, welding can be used for all measures of demand.

Help build the world! Welding and fabrication are used everywhere you look. The building you are in was erected by an ironworker; the piping that drains the sink water was installed by a plumber; the temperature and circulation in the room was done by a heating, ventilation, and air conditioning mechanic; the door frames installed by a carpenter.

Everywhere you look, some form of welding and fabrication was done by a tradesperson. Welding is the best common core for anyone trying out a hands-on trade. Welding can be done in residential, commercial, production, agriculture, and most forms of industry. This program gives you the best 28-week experience into the broad options that welding can amaze you with.

The skills and knowledge gained from this program will help students meet the necessary requirements to obtain placement in either union or non-union jobs.

Students perform welding and cutting on carbon steel using shielded metal arc welding (SMAW), gas metal arc welding (GMAW), flux cored arc welding (FCAW), metal cored arc welding (MCAW), gas tungsten arc welding (GTAW), oxy-fuel welding and cutting (OFW/OFC), plasma arc cutting (PAC), and carbon arc cutting with air/gouging (CAC-A). They gain knowledge of processes like brazing (B), braze welding (BW), soldering (S), and learn about stainless steel (SS) and aluminum (AI). Students work with augmented reality welding simulators, learn about rigging, hoisting, and knots. Students are also introduced into the workplace hazardous materials information system (WHMIS) and basic first aid.
